' Application filed May 7, 1915. Serial No. 26,642. u

To all whom it may concern:

Be it known that we, JOHN E. HUGHES and THOMAS A. CURRY, citizens of theUnited States, residing at Long Point, in the county of Livingston andState of Illinois, have invented new and useful Improvements inMilking-Stools, of which the following is a specification.

The invention relates to milkingj stools, and more particularly to theclass of clamp hangers for milking stools.

The primary object of the invention is the provision of a hanger of thischaracter wherein the milking stool or seat can be conveniently attachedto a stall for a cow within a stable and detached therefrom at will, thehanger being of novel construction to secure the firm and securemounting of the stool 0r seat for use.

Another object of the invention is the provision of a hanger of thischaracter where-.

in the aws for clamping the same to a support are closed to grip thelatter when the seat is occupied so that there is no possibility of thehanger becoming loose while in use. 1

Another object of the invention is the provision of a hanger of thischaracter which is simple in construction, reliable and efiicient inoperation, strong, durable and inexpensive in manufacture.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will: behereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claims hereunto appended;

In the drawing :Figure 1 is a perspective view of the milking stoolhanger-constructed in accordance with the invention applied to apartition pipe of a cow stall.'

Fig. 2 is a perspective view showing the hanger open ready forapplication to the stall. Fig, 3 is a vertical transverse sectionalview. 'Fig. t is a fragmentary longi-Q tudinal sectional view. 1

S1m1lar reference charactersmdicate corresponding parts throughout theseveral from the said pipe.

tion 6, the fork of which provides a Seat for the partition pipe'A, andthis arm iscon structed with a bifurcation? in which is swinginglysupported a bar 8 mounted upon the pivot 9 which is passed through thebi-,

furcated end of the arm 5 and also through the said bar for "permittingthe swinging movement of the latter, the inner end of the said bar beingformed with a notch 10 to receive a stop pin 11 which is engaged in thearm 5 and passed transversely through the bifurcation 7 to limit theswinging of the Patented May 30,

bar 8 and to sustain it in parallel relation to the straight portion ofthe said arm. The

bar 8 is formed with a reduced outer end 12 on which is slidablyfittedthe clip 13 carried by the seat 14 for the detachable mounting'of thelatter thereon.

Arranged upon the straight portion of the arm 5 is a pair of bell cranklevers 15 formed at their outer ends with outwardly bowed jaws 16, whileloosely connected to their inner ends are links 17 ,the same being alsopivotally connected to the bar 8 so that on the swinging'of the latterin one direction 7 I the levers 15 will be moved to bring the jaws Vinto clamping engagement with the pipe A,

and on reverse swinging movement of the bar 8'the levers will'bereversely moved for the opening of the jaws to release the hanger vThese levers 15 have their pivot 18- connectingthe same mounted in thestraight portion of the arm 5, and the,

jaws 16 cooperate with the forkedend 6 of the said arm for the firmandsecure clamping of the hangerupon the pipe A when the seat 14: isto'be occupied by the user.

; 'Fromthe foregoing description, takenin connection with theaccompanying drawing,

the construction and manner ofoperation of the device. will be clearlyunderstood, and

therefore, a more extended explanation has been omitted. I

V What is claimed is: I I

1. A seat hanger comprising a brace arm having. a fork terminal forminga seat for a support, a bar swingingly connected to the opposite end ofthe brace arm, a pair of jaw levers pivotally mounted on the arm, and

link connections between the said levers and r the bar for the openingand closing of the levers on swinging movement of the bar.

2. A seathanger comprising a brace arm having a fork terminal forminga'seat for a;

support, a bar swingingly connected tolthe opposite end of the bracearm, a pair of jaw vers on swinging movement of the bar, a seat having aclip detachably engaged on the bar, a stop pin mounted on the arm for 15limiting the swinging movement of the bar in one direction.

In testimony whereof we affix our signatures in presence of twowitnesses.
